T o all whom t may concern:

Be it known that I, ZAoH OLssoN, a'citizen of Sweden, Aand resident of the city of New York, in the kcounty of New York and State of New York, have inventedcertain new and useful Improvements 'in Tire-Filling Apparatus, 'of which the following is a specifica'- tion.

This invention isa means fork replacin the airv in a pneumatic tire `with a soli chemical compound having resilient prop orties.

The invention involves primarily, a means for mixing and injecting into an automobile tire a chemical composition which will form a solid resilient material 'entirely filling the tire, and taking the place'of the 4air which formerly occupied the tire. l

A number of processes and mechanisms for accomplishing this general result have heretofore been developed, in one of which is used amain charging vessel provided with an agitator, in which one of the ingredients to be used is contained, and there is also provided an auxiliary charging ves- ,sel in which another ingredient for mixing 'with the first ingredient for forming a re.- sulta'nt resilient material, is contained. The mechanical arrangement is such that the ingredient from the auxiliary charging vessel is injected into the material from the 'main vessel during the passage of the rmaterial to the tire, but is not mechanic allyV and thoroughly intermixed with the material from the, main vessel.

None of the processes which have heretofore been used contemplate the necessity of thoroughly intermixiiig thefingredieii'ts from separate tanks and feeding them continuously as the mixing process is carried out into the tires, `and it the particular object 'of this invention to provide a structure in which two ingredients which rapidly set `when brou ht together, are continuously fed into a Inecanicalfeeder and agitator, and are, by such feeder, and agitator fed to the tire simultaneously with the feed of the ingredients to :the feederiand agitator. By continuoi s feed, I havereference to the .cycle fromt e heginning vof the charge, that ,mixiiigthe two ingredients to the 'eii'd of the chare'that is, when the tire is letelyohlle I ,w ...ha ma, yes asser-theme11,-

" ls'iilshi 4which I piovide, ingredients may be successfully used in the tire-liling :process of such sensitiveness arid rapidity of action as vcould not be successfully used iii theiiiechan'isms heretofore used for accomplishing this general purpose. Y In 'carrying my invention into practice, I make use of la 'pair of tanks for containing they ingredients, which, when mixed will farm the regiment finer for the are, ani `provide meanswhereby the tanks may be 'subjected to air pressure for forcing the ingrdients therefrom. l I further provide a mechanical mixer and agitator ,into which the unmixed ingredients 'are fed from. "the tanks 'and from which the mixed ingredients f or forming 'the ll'e'r are injected into the tire, whereby the process of mechanically mixing 'and afgitati'rig the ingrdiehits and forcing the resultant mitI-fe into. the t'iie may be continuoiisly carriedfout. It 'is thns 'seen that vI can use sensitive iiigredients which necessitates thorough mixture immediately prior to their injection into the tire.

As has been heretofore pointed ont', mechanisms accomplishing a Yinii'ztii'r'e of the in2- gredients before they tenter the tire have been used, but such Ainechariisns do not 'contemplate the complete interinixture of the vingredients or the use Iof such sensitive iii- 'gradients as I employ in carrying `out my 8 method.v Y y y In the drawings which form a part of this application, and in which Vsimilar characters of reference indicate 'similar parts throughout the various views 'Figure 1 represents an elevational view of an apparatus constructed according to my invention, and l v Fig. represents a longitudinal sectional viewltake'n through the mixer. ,Y

Referring more 'particularly to the drawing, 5 and 6 represent thetanks in which the ingredients to be mixed are contained. Compressed air, or other suitable ,I gas,

from a source of supply. may be admit- 100 ted to the tanks :through a `pipe l provided witha 'pressure gage 2,2, and with'a ciito'f vfalvfe 2, and` through branchpipes 24 :and 25, Vrespectively.,v to the tanks 5 and 6.V The "pipes 24 and 25 are provided each wiaga 105 'conservaba 4 afnemer-'011mg *the Supply of @Ompi-essaim a the tanks.
